Wireless Charging at CEA

1. Wireless Charging at CEA Megan Hayes Senior Manager, Technology & Standards mhayes@CE.org

2. CEA Task Group • Created in July 2010. • Had 6 months to develop a recommendation regarding standardization within CEA. • Recommended the creation of a standing working group to address technology issues related to wireless charging.

3. Task Group Findings • Wireless charging is an emerging technology in consumer electronics with products entering the market in 2009. Examples include the Palm Pre, the Dell Latitude Z, and the aftermarket wireless chargers for the Wii game controllers. • The wireless technologies fall into one of four categories: a) magnetic induction, b) radio frequency/microwave, c) optical/infrared, and d) conduction • Classification based on the customer experience is a simple way to describe the sub-classes of technology • For magnetic induction technology, the technology can be classified as either close-range or mid-range. • For radio frequency/microwave and optical/infrared, the sub-classification is ambient or directed energy

4. Task Group Findings • Safety requirements must be addressed. Misimpressions about the safety of wireless power technology could hinder consumer acceptance and market growth. Therefore, a plan is needed to; • identify the latest safety standards applicable to wireless power • monitor the latest research and science associated with wireless power • develop communications and outreach plans to government agencies, the public, and media that will provide information on the safe use of wireless power technology

5. Task Group Findings • Efficiency is an issue that is will need to be defined and addressed • The consumer electronics industry is facing greater pressures on efficiency ratings. For example, Flat panel TVs are being regulated to meet certain energy requirements • Interoperability is an issue that needs to be defined and addressed, but after the technologies have been proven and accepted by the marketplace. Interoperability can happen at different levels • Within a given technology and a particular subclass • Within a given technology and all subclasses • Among different technology types and particular technology subclasses • Among any combination of different technologies and subclasses

6. Task Group Recommendations • That CEA establish a standing working group to address technical issues related to wireless charging technologies. The recommended scope of the group is to develop standards, recommended practices, and related documentation related to wireless charging. • Since wireless charging is an emerging market, the task group believes that some of the issues should be addressed in near term. The task group believes that addressing these near term issues can result in the standardized nomenclature, terms, and definitions. This will then facilitate the dialog among stakeholders. • Other issues can be addressed in the longer term when the market begins to mature. These issues would lead to standards and guidelines that are prescriptive in nature, that is, technical requirements on the features, functions, and performance of a wireless charging component, device, or system.

7. Task Group Recommendations • Near term issues (Low hanging fruit) • Nomenclature for technology types, subclasses, and their definitions • White paper on RF safety and emissions regulations • Definition for power transfer efficiency • Requirements for standby power to offset wider efficiency ranges • Nomenclature for power output and definitions

8. Task Group Recommendations • Longer term issues (Higher hanging fruit) • Nomenclature for type of interoperability and definitions • User interface symbols and meanings • Prescriptive standards on functionality of each type of interoperability
